> Subclasses of ResourceID may not to be serializable

> Key: FLINK-3972
> URL: https://issues.apache.org/jira/browse/FLINK-3972
> Project: Flink
> Issue Type: Bug
> Components: ResourceManager
> Affects Versions: 1.1.0
> Reporter: Maximilian Michels
> Assignee: Maximilian Michels
> Priority: Minor
> Fix For: 1.1.0
>
>
> WorkerTypes are currently subclasses of ResourceID. ResourceID has to be
> Serializable but its subclasses don't. This may lead to problems when these
> subclasses are used as ResourceIDs, i.e. serialization may fail with
> NotSerializableExceptions. Currently, subclasses are never send over the wire
> but they might be in the future.
> Instead of relying on subclasses of ResourceID for the WorkerTypes, we can
> let them implement an interface to retrieve the ResourceID of a WorkerType.
